Lanthanides and Actinides
The application of quantum chemistry to systems containing atoms of the lanthanide (57La 71Lu) and/or actinide (90Th 103Lr) series is a considerable challenge and has been attempted only by a comparatively small number of researchers. Several complications, some of which will be described in the following, prevent standard quantum chemical approaches from being successful in this field in all r...
متن کاملAPPLICATION OF PLASMA EROSION OPENING SWITCHES TO HIGH POWER ACCELERATORS FOR PULSE COMPRESSION AND POWER MULTIPLICATIONt
There has been considerable interest in recent years in using inductive storage techniques for pulsed power applications. Some of the advantages that inductive generators have over the more conventional capacitive systems include higher final stage energy density for higher power and smaller generators, lower insulator stress, faster pulse risetime, and the possibility of shorter pulse length. ...
متن کاملSolubility and hydrolysis of tetravalent actinides
presented. The hydrolysis constants are selected preferentially from experimental studies at actinide trace concentrations, where the interference of colloid formation can be excluded. Unknown formation constants of mononuclear complexes An(OH)n are estimated by applying a semi-empirical electrostatic model and an empirical correlation with the known constants of other actinide ions. Based on t...
متن کاملCoordination Chemistry of the Actinides
recognize +4 and +6 as the main oxidation states for uranium and +4 as the only important oxidation state for thorium; appreciate that coordination numbers of >6 are the norm; be familiar with the main features of the chemistry of the other actinides, and appreciate the transition in chemical behaviour across the series; appreciate the importance of nitrate complexes; recognize the characterist...
متن کاملNuclear waste forms for actinides.
The disposition of actinides, most recently 239Pu from dismantled nuclear weapons, requires effective containment of waste generated by the nuclear fuel cycle. Because actinides (e.g., 239Pu and 237Np) are long-lived, they have a major impact on risk assessments of geologic repositories. Thus, demonstrable, long-term chemical and mechanical durability are essential properties of waste forms for...
